The Owls Under-21s began their league campaign with a 3-2 win over Coventry at Hillsborough on Monday.
The visitors took an early lead from the penalty spot as Mathieu Manset fired home from 12 yards but Wednesday were back on level terms almost immediately from the restart.
A fine through ball from Paul Corry picked out Caolan Lavery, who kept his composure to round the goalkeeper and place into the empty net.
Coventry regained their lead in the 47th minute when Lewis Rankin slotted past Adam Davies after good City build-up play.
But the impressive Lavery put the Owls back on level terms in the 53rd minute.
The striker controlled a long ball forward from Rhys McCabe, cut inside his marker and drilled home into the bottom corner.
Khallil Lambin then rattled the upright with a fierce strike before McCabe settled the game with an accurately placed free kick from 20 yards.
Under-21 Head Coach Lee Bullen said: “The three goals we did score were very pleasing but we should have been out of sight with the chances we created.
“Caolan scored two goals of really good quality and then Rhys has settled it with a free kick, so that was pleasing.
“The game was a good learning process for the young lads to play with senior players and to take on more responsibility during the game.
“Playing at Hillsborough will be a big factor for the boys this year because, although it was only a small crowd, it’s important they get used to playing here.”
